In this research, the results of a hydro-chemical study of Lake Kopa in Kazakhstan are described, in the
context of the regional geography and aggravating ecological problems of the lake. Besides analyzing
the concentrations of all major ions, heavy-metal ions and other pollutants, their vertical and
horizontal distribution were also assessed. Moreover, water pollution indices (WPI) were calculated
for individual ions, classes of pollutants, and total pollution, revealing serious overload of human-
induced pollution within the lake’s ecosystem. Concentrations of major ions and WPI were monitored
over 2009-2013 period, revealing a distinct seasonal pattern and a multi-year periodicity in respect to
the measured parameters. In addition, studying ion exchange between lake water and bottom
sediment showed complex non-equilibrium processes besides leaching out Ca2+ and its exchange for
Na+.
